River Dredging Machine Sand Pump

Product Description

Type DGD gravel pumps are designed for continuous handling the most difficult higher abrasive slurries which contain too big solids to be pumped by common pump. They are suitable for delivering slurries in Mining, Explosive sludge in metal melting. Dredging in dredger and course of rivers, and other fields.

Construction of this pump is of single casing connected by means of clamp bands and wide wet passage. The wet parts are made of Ni-hard and high chromium abrasion-resistance alloys. The discharge direction of pump can be oriented in any direction of 360 degree. This type of pump possesses the advantages of easy installation and operation, good performance of NPSH and abrasion-resistance.

Product Application

Dredging and relevent projects.

Performance range

Size:4-16inches

Capacity:36-5040m3/h

Head:5-80m

Material:Cr27,Cr28,

Seal:packing seal,expeller seal,mechnical seal.

Main Features

A large percentage of duties allow the use of the ce ntrifugal seal which eliminates the need of sealing water.
Gland shaft seal
A packed gland type shaft seal is also available and can be fitted with a low flow or a full flow flush seal water arrangement.
Shaft and bearing assembly
A large diameter shaft with a short overhang minimizes deflection and vibration.Heavy-duty roller bearings are housed in a removable bearing cartridge.
Pump Base
A minimum number if through bolts hold the pump casing to the frame .A means of impeller adjustment is provided in a convenient position below the bearing housing.
Outer Casing

Split outer casing halves of cast or ductile iron contain the wear liners and provide high operation pressure capabilities.
Impeller
The impeller may be either moulded elastomer or hard metal.Deep side sealing vanes relieve seal pressure and minimize recirculation.

Cast-in impeller threads are better suited for slurries.
Interchangeable hard metal and moulded elastomer liners.
Mating faces in hard metal liners are tapered to allow positive alignment during assembly and allow components to be easily removed for replacement.
Hydraulic seal rings give positive sealing between mating faces.
